Okay fair, I just always think of NVMe drives with 5000-7000 MB/s read speed when M.2 gets mentioned and I misremembered that SATA (non M.2) SSDs were cheaper.

- Havoc 2y agoPretty sure the rasps are single lane gen 3. So 1 gig a sec max
- SushiHippie 2y agoSecond sentence in TFA is: > It provides fast (up to 500 MB/s) data transfer
- zamadatix 2y agoNeither of these takes is necessarily incorrect. Officially yes, out of the box it's 1x PCIe 2.0 and you get ~500 MB/s. There is also an boot flag to switch the PCIe from 2 to 3 and it doubles the speed to ~1000 MB/s. That mode is not officially certified as PCIe 3.0 compliant though due to the way its run but it seems to work for just about anything so long as you don't use a really long ribbon cable. https://www.jeffgeerling.com/blog/2023/forcing-pci-express-gen-30-speeds-on-pi-5 https://www.jeffgeerling.com/blog/2023/forcing-pci-express-g...
